CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of International Application No. PCT/CN2014/079950, filed on Jun. 16, 2014, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for presenting a panoramic photo in a mobile terminal, and a mobile terminal.

BACKGROUND

With the rapid development of communications technologies, functions of a mobile terminal become increasingly powerful, and a range and an environment in which a mobile terminal is used become increasingly diverse. For example, currently, many mobile terminals such as mobile phones, personal digital assistants, and personal computers all have a function of panoramic photographing.

When a mobile terminal performs panoramic photographing, a user rotates the mobile terminal to photograph a scene that needs to be photographed. A basic principle of “panoramic photographing” is that edge parts of two photos are searched for, and registration is performed on areas that have closest imaging effects, so as to complete automatic stitching of the photos. Multiple photographed photos may be then stitched as one panoramic photo according to the foregoing stitching principle, and a vision of a scene recorded in the panoramic photo is relatively broad. When browsing a photo, a user may browse relatively rich image content on a panoramic photo, which features a relatively strong visual impact.

However, although currently, relatively rich photo content can be recorded in a panoramic photo, the photo is relatively large when the panoramic photo is presented in a mobile terminal. When browsing the panoramic photo, a user needs to manually slide the photo to browse the photo content, which is relatively complex in terms of operations.

DESCRIPTION OF EMBODIMENTS

The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

According to a method for presenting a panoramic photo in a mobile terminal provided in the embodiments of the present invention, a panoramic photo moves as the mobile terminal rotates. For ease of description in the embodiments of the present invention, a browsing mode in which a panoramic photo moves as the mobile terminal rotates is referred to as an “immersive browsing mode”, and a browsing mode of a panoramic photo in the prior art is referred to as a normal mode in the following, which is certainly not limited thereto; for example, the “immersive browsing mode” may also be referred to as “panorama browsing mode”. When browsing a panoramic photo that is displayed in a normal mode in the mobile terminal, a user may choose to enter the immersive browsing mode. In the immersive browsing mode, the panoramic photo may be browsed by rotating the mobile terminal, and it is not required to manually slide on a screen of the mobile terminal to browse the panoramic photo.

FIG. 1 shows a flowchart of implementation of a method for presenting a panoramic photo in a mobile terminal according to an embodiment of the present invention. The method may be performed by a mobile terminal, or specifically by components in the mobile terminal. As shown in FIG. 1, the method includes the following steps:

S101: Detect a trigger instruction that is used to instruct the mobile terminal to enter an immersive browsing mode.

In this embodiment of the present invention, if the trigger instruction that is used to instruct the mobile terminal to enter the immersive browsing mode is detected, S102 is performed.

S102: Detect and determine a rotation angle of the mobile terminal.

S103: Move and present, according to the rotation angle determined in S102, a panoramic photo that is displayed in a normal mode in the mobile terminal.

According to the method for presenting a panoramic photo in a mobile terminal provided in this embodiment of the present invention, when a trigger instruction that is used to instruct the mobile terminal to enter an immersive browsing mode is detected, a rotation angle of the mobile terminal is detected and determined; and a panoramic photo that is displayed in a normal mode in the mobile terminal is moved and presented according to the determined rotation angle. By using the present invention, a panoramic photo may be enabled to move as a mobile terminal rotates, so that browsing of the panoramic photo may be implemented without requiring manual sliding on a screen of the mobile terminal, which is easy and convenient in terms of operations.

In this embodiment of the present invention, there may be multiple implementation manners for specifically implementing a rotation process of the mobile terminal. For example, a user may rotate the mobile terminal in a predefined manner immediately after the user triggers the mobile terminal to enter the immersive browsing mode, where the predefined manner may be obtained, for example, by pre-learning from a user manual. For example, after the user triggers the mobile terminal to enter the immersive browsing mode, the mobile terminal may further provide prompt information that is used to instruct to rotate the mobile terminal, so as to prompt the user to perform rotation.

An implementation manner in which a mobile terminal provides prompt information that is used to instruct to rotate the mobile terminal is used as an example in an embodiment of the present invention in the following to describe in detail the method for presenting a panoramic photo in a mobile terminal involved in the foregoing embodiment.

FIG. 2 shows another flowchart of implementation of a method for presenting a panoramic photo in a mobile terminal according to an embodiment of the present invention. The method may be performed by a mobile terminal, or specifically by components in the mobile terminal. As shown in FIG. 2, the method includes the following steps:

S201: Detect a trigger instruction that is used to instruct the mobile terminal to enter an immersive browsing mode.

In this embodiment of the present invention, a user may input, by using a display screen or a key of the mobile terminal, the trigger instruction that is used to instruct the mobile terminal to enter the immersive browsing mode. For example, in this embodiment of the present invention, an enabling control used to enable the immersive browsing mode may be set on a display interface of the mobile terminal. An enabling status of the enabling control is used to determine whether to enable the immersive browsing mode, and when it is detected that the enabling control is enabled, it can be determined that the mobile terminal needs to enter the immersive browsing mode. For example, an immersive browsing button is set on the display interface of the mobile terminal. When choosing to enter the immersive browsing mode to browse a panoramic photo, the user can trigger the button, to instruct the mobile terminal to enter the immersive browsing mode; and if the mobile terminal receives the trigger instruction, it may be considered that the user needs to browse the panoramic photo in the immersive browsing mode.

Optionally, in this embodiment of the present invention, the user may be further prompted, when it is detected that the user is browsing a panoramic photo, to trigger the enabling control that is used to instruct to enable the immersive browsing mode.

S202: When the trigger instruction that is used to instruct the mobile terminal to enter the immersive browsing mode is detected, provide prompt information that is used to instruct to rotate the mobile terminal.

In this embodiment of the present invention, in order to implement immersive mode browsing, the user needs to rotate the mobile terminal, so that the panoramic photo can move as the mobile terminal rotates. Generally, for better browsing of the panoramic photo, the prompt information that is used to instruct to rotate the mobile terminal may be provided to notify the user that the mobile terminal needs to be rotated according to a preset direction, where the preset direction may be, for example, rotating from left to right, and certainly, may also be rotating from right to left.

In this embodiment of the present invention, the provided prompt information may be text information displayed on the display interface, and certainly, may also be voice information notified by means of a voice output, which is not specifically limited in this embodiment of the present invention.

Optionally, in this embodiment of the present invention, a rotation direction of the mobile terminal that is saved when the panoramic photo is photographed may be further acquired, and the acquired rotation direction is notified in a form of prompt information; prompt information that is used to instruct to rotate the mobile terminal according to the notified rotation direction is provided to prompt the user to rotate the mobile terminal according to the acquired rotation direction of the mobile terminal that is saved when the panoramic photo is photographed.

S203: Detect and determine a rotation angle of the mobile terminal.

In this embodiment of the present invention, the rotation angle of the mobile terminal is detected in real time, so as to control, in a timely manner, the panoramic photo to move.

When photographing the panoramic photo, the user generally positions the mobile terminal in a determined placement direction. However, when browsing the panoramic photo, the user may be much likely to use a placement direction different from the determined placement direction in photographing the panoramic photo to browse the panoramic photo. Therefore, in this embodiment of the present invention, in order to browse the panoramic photo in a relatively precise manner, the rotation angle of the mobile terminal may be determined according to a placement direction in which the mobile terminal is located in a rotation process.

A process of determining the rotation angle of the mobile terminal in S203 in this embodiment of the present invention may use the following manner for the determining as shown in FIG. 3.

S2031: Determine a placement direction in which the mobile terminal is located in a rotation process.

S2032: Determine a rotation angle of the mobile terminal according to the placement direction determined in S2031.

In this embodiment of the present invention, the placement direction in which the mobile terminal is located may be determined by using a gravity direction of the mobile terminal indicated by a gravity sensor disposed in the mobile terminal, and the rotation angle of the mobile terminal is determined by using an angle of a gyro sensor disposed in the mobile terminal. Optionally, in this embodiment of the present invention, the gravity sensor used to determine the placement direction of the mobile terminal and the gyro sensor used to determine the rotation angle of the mobile terminal may be enabled when the trigger instruction that is used to instruct the mobile terminal to enter the immersive browsing mode is detected.

Optionally, the determining the placement direction in which the mobile terminal is located in the rotation process in S2031 in this embodiment of the present invention may use a method shown in FIG. 4 for the determining. As shown in FIG. 4, the method includes the following steps:

S2031 a: Establish, based on a plane in which a screen of the mobile terminal is located, a reference three-dimensional coordinate system.

In this embodiment of the present invention, the reference three-dimensional coordinate system may be established based on the plane in which the screen of the mobile terminal is located, where an X-Y plane of the reference three-dimensional coordinate system is parallel to the plane in which the screen of the mobile terminal is located, and a Z-axis of the reference three-dimensional coordinate system is perpendicular to the plane in which the screen of the mobile terminal is located.

The mobile terminal is located at different placement directions in the rotation process, and a corresponding reference three-dimensional coordinate system also rotates according to the different placement directions of the mobile terminal. For example, schematic diagrams of reference three-dimensional coordinate systems are separately corresponding to a vertical placement direction in FIG. 5A and a horizontal placement direction in FIG. 5B.

S2031 b: Detect an angle of a gravity direction of the mobile terminal with respective to a direction of an X-Y plane of the reference three-dimensional coordinate system established in S2031 a.

S2031 c: Determine the placement direction in which the mobile terminal is located in the rotation process according to the angle, obtained by means of detection in S2031 b, of the gravity direction of the mobile terminal with respective to the direction of the X-Y plane of the reference three-dimensional coordinate system.

Optionally, in this embodiment of the present invention, in order to simplify a control process of controlling presentation of the panoramic photo, when the angle of the gravity direction of the mobile terminal with respective to the direction of the X-Y plane of the reference three-dimensional coordinate system is not greater than 45 degrees, it may be determined that the placement direction in which the mobile terminal is located in the rotation process is a vertical placement direction; and when the angle of the gravity direction of the mobile terminal with respective to the direction of the X-Y plane of the reference three-dimensional coordinate system is greater than 45 degrees, it may be determined that the placement direction in which the mobile terminal is located in the rotation process is a horizontal placement direction.

It should be noted that in this embodiment of the present invention, when the angle of the gravity direction of the mobile terminal with respective to the direction of the X-Y plane of the reference three-dimensional coordinate system is equal to 45 degrees, it may be determined that the placement direction in which the mobile terminal is located is the vertical placement direction, or is the horizontal placement direction, and may be specifically set to the vertical placement direction in this embodiment of the present invention.

In this embodiment of the present invention, if the placement direction in which the mobile terminal is located in the rotation process is determined by using the angle of the gravity direction of the mobile terminal with respective to the direction of the X-Y plane of the reference three-dimensional coordinate system in S2031, a determining manner shown in FIG. 6 may be used when determining the rotation angle of the mobile terminal is performed in S2032:

S2032 a: Determine a corresponding axial direction of the mobile terminal in the rotation process.

In this embodiment of the present invention, when it is determined that the placement direction in which the mobile terminal is located in the rotation process is the horizontal placement direction, a direction of the Z-axis in the reference three-dimensional coordinate system is used as the corresponding axial direction of the mobile terminal in the rotation process; or when it is determined that the placement direction in which the mobile terminal is located in the rotation process is the vertical placement direction, a direction of an X-axis or a direction of a Y-axis in the reference three-dimensional coordinate system is used as the corresponding axial direction of the mobile terminal in the rotation process.

It should be noted that in this embodiment of the present invention, the foregoing corresponding axial direction of the mobile terminal in the rotation process is merely to simplify a process of determining the rotation angle of the mobile terminal, and a specific determining manner is not limited thereto.

S2032 b: Use an angle by which the mobile terminal rotates with respective to the axial direction determined in S2032 a as the rotation angle of the mobile terminal.

In this embodiment of the present invention, the gyro sensor used to determine the rotation angle of the mobile terminal may be enabled when the trigger instruction that is used to instruct the mobile terminal to enter the immersive browsing mode is detected. An angle by which the gyro sensor disposed on the mobile terminal rotates with respective to the axial direction is detected, and the rotation angle of the mobile terminal with respective to the corresponding axial direction is determined according to the angle by which the gyro sensor rotates.

S204: Move, according to the determined rotation angle of the mobile terminal, a panoramic photo that is displayed in a normal mode in the mobile terminal.

In this embodiment of the present invention, when a panoramic photo is browsed, the panoramic photo is generally first displayed in a normal browsing mode; for example, it may be that a panoramic photo with a relatively low resolution, or only a part of the panoramic photo such as a leftmost part of the panoramic photo or a rightmost part of the panoramic photo is displayed in a display screen of the mobile terminal. In this embodiment of the present invention, after the rotation angle of the mobile terminal is determined, the panoramic photo that is displayed in the normal mode in the mobile terminal may be moved to implement immersive browsing of the panoramic photo.

Optionally, in this embodiment of the present invention, multiple implementation manners may be used for moving the panoramic photo that is displayed in the normal mode in the mobile terminal. For example, the panoramic photo that is displayed in the normal mode in the mobile terminal may be moved along a direction the same as the rotation direction of the mobile terminal, and the panoramic photo may also be moved along a direction opposite to the rotation direction of the mobile terminal. In this embodiment of the present invention, in order to implement a better display effect, preferably, the panoramic photo that is displayed in the normal mode in the mobile terminal is moved along the direction opposite to the rotation direction of the mobile terminal.

Optionally, in this embodiment of the present invention, in order to implement smooth moving of the panoramic photo, a rotation angle threshold may be preset, and before S204 is performed, it is determined that the rotation angle of the mobile terminal reaches the preset rotation angle threshold. When the panoramic photo is browsed in the immersive browsing mode, the rotation angle of the mobile terminal is detected in real time; and when the rotation angle of the mobile terminal reaches the preset rotation angle threshold, the panoramic photo is controlled to move, which implements smooth moving of the panoramic photo. If the preset rotation angle threshold is not reached, the panoramic photo may not be moved.

In this embodiment of the present invention, the moving, according to the determined rotation angle of the mobile terminal, the panoramic photo that is displayed in the normal mode in the mobile terminal along the direction opposite to the rotation direction of the mobile terminal in S204 may use an implementation manner shown in FIG. 7 (when the panoramic photo is moved along the direction the same as the rotation direction of the mobile terminal, a similar manner may also be used):

S2041: Determine whether the rotation angle of the mobile terminal reaches the preset rotation angle threshold; if the rotation angle of the mobile terminal reaches the preset rotation angle threshold, perform S2042; otherwise, perform S202 to detect the rotation angle of the mobile terminal.

S2042: When the rotation angle reaches the preset rotation angle threshold, move the panoramic photo that is displayed in the normal mode in the mobile terminal along a direction opposite to the rotation direction of the mobile terminal.

Optionally, in this embodiment of the present invention, in order to further enhance an effect of smooth moving, a minimum displacement may be further determined, and when being controlled to move along the direction opposite to the rotation direction of the mobile terminal, the panoramic photo is moved for the determined minimum displacement each time. A unit of the minimum displacement is pixel.

In this embodiment of the present invention, the minimum displacement of the panoramic photo may be determined according to the preset rotation angle threshold, a rotation angle of the mobile terminal when the panoramic photo is photographed, and a photo width of the panoramic photo along a rotation direction of the mobile terminal when the panoramic photo is photographed. The rotation angle of the mobile terminal when the panoramic photo is photographed and the photo width of the panoramic photo along the rotation direction of the mobile terminal when the panoramic photo is photographed are generally recorded and saved when the panoramic photo is photographed, which may be directly obtained from a relevant attribute of the panoramic photo that is saved when the panoramic photo is photographed in this embodiment of the present invention. It should be noted that in this embodiment of the present invention, a unit of the photo width of the panoramic photo is also pixel.

Optionally, in this embodiment of the present invention, the determining the minimum displacement of the panoramic photo may use the following manner. The minimum displacement of the panoramic photo is determined according to a formula

${s = {d\frac{\varphi_{1}}{\varphi_{2}}}},$ where s is the minimum displacement of the panoramic photo; d is the photo width of the panoramic photo; φ₁ is the preset rotation angle threshold; and φ2 is the rotation angle of the mobile terminal when the panoramic photo is photographed.

In this embodiment of the present invention, for the browsed panoramic photo, when the panoramic photo is determined, the photo width d of the panoramic photo and the rotation angle φ2 of the mobile terminal when the panoramic photo is photographed are fixed values (if the rotation angle φ2 is recorded in a process of photographing the panoramic photo, the recorded value is used; and if the rotation angle φ2 is not recorded during photographing, some reference values, such as 180 degrees or 360 degrees, may be used as the rotation angle); therefore, in this embodiment of the present invention, in order to implement smooth moving of the panoramic photo, an appropriate rotation angle threshold φ₁ may be preset. If the preset rotation angle threshold φ₁ is fixed, the minimum displacement for which the panoramic photo is moved in the rotation process is determined. In a process of browsing the panoramic photo, the rotation angle of the mobile terminal is detected and determined in real time, and if it is determined that the rotation angle of the mobile terminal reaches the preset rotation angle threshold φ₁, the panoramic photo is moved for the minimum displacement along a direction opposite to the rotation direction of the mobile terminal.

In this embodiment of the present invention, the rotation angle of the mobile terminal may be an angle difference between an angle corresponding to a current position of the mobile terminal and an angle corresponding to a position of the mobile terminal when the panoramic photo is moved for a previous time (if it is the first time to determine the rotation angle of the mobile terminal, it may be considered that a corresponding angle of the mobile terminal is 0 when the panoramic photo is moved for a previous time). In this embodiment of the present invention, a process of determining whether the rotation angle of the mobile terminal reaches the preset rotation angle threshold may be understood as a continuously executed and reset process, that is, each time the rotation angle of the mobile terminal reaches the preset rotation angle threshold φ₁, an initial rotation angle of the mobile terminal may be set to 0, the rotation angle is detected and determined, and the panoramic photo is moved according to whether the determined rotation angle reaches the preset rotation angle threshold. For example, the initial rotation angle of the mobile terminal is set to 0, and in a process in which the mobile terminal rotates from 0 degree to φ₁−1 degrees, the panoramic photo does not move; when the mobile terminal rotates to φ₁ degrees, the panoramic photo moves for the minimum displacement, the rotation angle is reset, and the rotation angle of the mobile terminal continues to be detected; and when the mobile terminal rotates to φ₁ degrees, the panoramic photo moves for the minimum displacement again, which is repeated until the mobile terminal stops rotating.

Further, in this embodiment of the present invention, a process of moving the panoramic photo may be an immediately executed process, that is, the panoramic photo is moved once it is determined that the rotation angle of the mobile terminal reaches the preset rotation angle threshold; for example, the preset rotation angle threshold φ₁ is 5 degrees, the panoramic photo is moved for the minimum displacement once the rotation angle reaches 5 degrees. The process of moving the panoramic photo may also be a process executed with delay, that is, the panoramic photo is moved for the minimum displacement within a period of time after it is determined that the rotation angle of the mobile terminal reaches the preset rotation angle threshold.

The rotation angle of the mobile terminal may further be a difference between the angle corresponding to the current position of the mobile terminal and the angle corresponding to the initial position of the mobile terminal, that is, the rotation angle of the mobile terminal may be a continuously accumulated value as a user moves the mobile terminal. In this case, a directly proportional relationship may be set between a displacement for which the panoramic photo moves and the rotation angle. That is, a larger rotation angle of the mobile terminal indicates a larger displacement for which the panoramic photo moves, and a smaller rotation angle of the mobile terminal indicates a smaller displacement for which the panoramic photo moves.

There may further be other embodiments for the foregoing manner of moving the panoramic photo and manner of determining manner of the minimum displacement, and specific implementation manners thereof are not limited in the present invention.

S205: Present the panoramic photo in the immersive browsing mode.

In implementation of panoramic photo browsing in an immersive browsing mode in this embodiment of the present invention, moving of the panoramic photo is implemented by rotating a mobile terminal instead of implementing moving of the panoramic photo by sliding the panoramic photo by using a finger. Another manner for presenting a panoramic photo may use an existing implementation solution, for example, when the panoramic photo is presented, an existing implementation manner may be used in a process of adapting the panoramic photo to a size of a display screen.

According to the method for controlling presentation of a panoramic photo provided in this embodiment of the present invention, when a trigger instruction that is used to instruct a mobile terminal to enter an immersive browsing mode is detected, a user is prompted to rotate the mobile terminal according to a set direction, and a placement direction in which the mobile terminal is located in a rotation process is determined, and a rotation angle of the mobile terminal in a corresponding direction is further determined according to the placement direction. A minimum displacement for which the panoramic photo moves is determined according to a preset rotation angle threshold, and the panoramic photo is moved for the minimum displacement along a direction opposite to a rotation direction of the mobile terminal and is presented. By using the present invention, a panoramic photo may be enabled to move as a mobile terminal rotates, so as to further implement browsing of the panoramic photo without requiring manual sliding on a screen of the mobile terminal to browse the panoramic photo, which is easy and convenient in terms of operations.

Therefore, in order to implement the method for presenting a panoramic photo in a mobile terminal provided in this embodiment of the present invention, the method may also differ from existing panoramic photo photographing during panoramic photo photographing.
